DETAILED DESCRIPTION

Described herein are modular mattress systems, methods, and devices that permit a high degree of customization, while providing one or more additional benefits as described below.

Each human body has different pressure points and comfort levels. It can be hard for a mattress of generally uniform construction to accommodate the different pressure points and spinal alignment of a single individual. It is even more difficult for a mattress to accommodate two individuals that share a common mattress, as the comfort and spinal alignment needs of each person likely differ. People generally throw away their mattresses and fill up landfills when their mattresses do not accommodate their comfort needs.

Often, mattresses are bulky, and usually have innerspring coils made of hard gauge steel for support. Shipping costs for mattresses are usually high, and mattresses can take up three times as much space in warehouses than they need. Mattresses fill up landfills when disposed of and the steel springs will never decompose.

The modular mattresses described herein may alleviate or eliminate one or more of these problems. For example, in some embodiments, a modular mattress as described herein may comprise lightweight separate sections that can selected and interchanged as needed. Thus a user can select sections that work for their individual needs as desired. Further, the lightweight sections can provide that the components are easy to ship because they can shipped compressed in small boxes. Further, the interchangeable components are replaceable as needed, thereby reducing the amount of parts being thrown in landfills. In some embodiments, bedbugs, dead skin, food crumbs, pet stains and other debris can be vacuumed and washed from the modular mattresses for a fresh sleep. People generally sleep better when their mattress is aligned with their body, and some embodiments of the mattresses described herein facilitate a custom fit for each unique individual.

The following discussion presents detailed descriptions of the several embodiments of modular mattress systems shown in the figures. These embodiments are not intended to be limiting, and modifications, variations, combinations, etc., are possible and within the scope of this disclosure.

FIGS. 1A-1C illustrate schematic representations of three embodiments of modular mattress systems 100 a, 100 b, 110 c (also referred to as modular mattresses 100 a, 100 b, 100 c, or collectively as modular mattress 100). As will be described below, the modular mattress 100 includes modular components that can be selected, added, removed, and/or replaced individually of the other components of the modular mattress 100. As described above, this can provide one or more of the following advantages, such as, improving customization and personalization of the modular mattress 100, permitting the function and feel of the modular mattress 100 to change over time to adapt to changing user preferences or other conditions, facilitating replacement of old, worn, or damaged components of the modular mattress 100, permitting the modular mattress to be easily cleanable, decreasing waste to landfills, and increasing shipping efficiency, among others.

The modular mattress 100 can include, for example, a removable ticking or cover 102. Example covers are shown in FIGS. 2A-2C and will be described in greater detail below. As shown in FIGS. 1A-1C, in general, the cover 102 is a fabric layer configured to surround and protect the internal components of the modular mattress 100. The internal components may comprise one or more comfort components (e.g., a comfort layer 104) and one or more support components (e.g., a support layer 106). In the illustrated embodiments, the comfort components and the support components are arranged in layers (e.g., the comfort layer 104 and the support layer 106) although this need not be the case in all embodiments.

The comfort components (e.g., the comfort layer 104) can be made from any of a variety of materials that contribute to the comfort and/or feel of the mattress. For example, in some embodiments, the comfort layer 104 comprises a memory foam (viscoelastic foam) layer, a latex layer, a pillow top layer, etc. In some embodiments, the comfort layer 104 may be between about 1 and 4 inches thick, although other thicknesses are possible. In some embodiments, the comfort layer 104 is about 2 inches thick.

The support components (e.g., the support layer 106) can be made of any of a variety of materials that contribute to the support and/or feel of the mattress. For example, the support layer 106 can comprise a layer of supportive foam. The support layer 106 can be provided in a variety of different levels of firmness. For example, the support layer 106 can be provided in extra soft, soft, medium, firm, extra firm. Although five firmness levels are identified here, it will be appreciated that the support layers 106 can be provided with greater or fewer firmness levels in some embodiments. In some embodiments, the support layer 106 is between about 4 and 12 inches thick, although other thicknesses are also possible. In some embodiments, the support layer 106 is about 8 inches thick. Additional examples of support layers are shown in FIGS. 3-6B described in greater detail below.

The modular mattress 100 is referred to as herein as “modular” because a user can easily select and individually replace the individual components of the modular mattress 100 to customize the mattress 100 as desired. For example, a user can select a desired comfort layer 104 from among a plurality of options (e.g., memory foam (viscoelastic foam), layer, pillow top, etc.) and select desired support layer 106 from among a plurality of options (e.g., extra soft, soft, medium, firm, extra firm, etc.) to customize the modular mattress 100. The selected components can be placed inside the cover 102 to assemble the mattress. Further, at any time, the user may make changes to the modular mattress 100 by replacing one or more of the components. For example, the user can replace a viscoelastic comfort layer with a latex comfort layer. Similarly, the user can replace a medium support layer with an extra firm layer. Additionally, the user can, at any time, replace the cover 102 without replacing the internal components. Accordingly, the modular mattress system 100 can provide the user with a highly customizable mattress that can be adjusted and varied over time as desired.

Further, the modular mattress system 100 can reduce waste to landfills as the whole modular mattress 100 need not be discarded. For example, if a support layer 106 becomes worn and needs to be replaced, the support layer 106 can be removed (leaving the cover 102 and the comfort layer 104), discarded, and replaced with a new support layer 106. Thus, rather than discarding the entire mattress as necessitated by conventional mattresses, the modular mattress system 100 described herein reduces waste to landfills by providing that individual components can be removed and replaced as necessary.

FIG. 1A illustrates the modular mattress 100 a, which includes the cover 102, surrounding a single comfort layer 104 positioned on top of a single support layer 106. The modular mattress 100 a may be provided in any size (such as twin, full, queen, king, etc.). As such, the conform layer 104 and the support layer 106 can each be provided in sizes (lengths and widths) that match common mattress sizes as twin, full, queen, king, etc. In the illustrated embodiment of FIG. 1A, the modular mattress 100 a is customizable because each of the comfort layer 104 and the support layer 106 can be selected and adjusted from among a plurality of options as described above. However, in the illustrated embodiment of FIG. 1A, because the comfort layer 104 and the support layer 106 extend entirely across the mattress, the embodiment of FIG. 1A may not allow customization or variation across the surface of the mattress.

FIG. 1B illustrates an embodiment of the modular mattress 100 b, which can allow customization and variation across the surface of the mattress. As shown, the modular mattress 100 b includes a comfort layer 104 made up of two comfort layer sections 104 a, 104 b that are arranged side by side. The modular mattress 100 b includes a support layer 106 made up of two support layer sections 106 a, 106 b that are arranged side by side. In this embodiment, each of the comfort layer sections 104 a, 104 b and each of the support layer sections 106 a, 106 b can be selected and adjusted from among a plurality of options increasing the degree to which the modular mattress 100 b can be customized. For example, the modular mattress 100 b can permit customization of the right side of the mattress that is different and separate from left side of the mattress. This may be advantageous for larger mattresses that are generally shared by more than one person, allowing each person to select customization options that work form them.

FIG. 1C illustrate another embodiment of the modular mattress 100 c that can be considered a hybrid of the modular mattress 100 a and the modular mattress 100 c. As shown, the modular mattress 100 c includes a single comfort layer 104, and a support layer 106 made up of two support layer sections 106 a, 106 b that are arranged side by side. In this embodiments, the support layer 106 can be customized on each of the right and left side of the mattress, but the support layer 104 (which extends across the entire mattress) cannot. Alternatively, the modular mattress 100 c could include a comfort layer 104 made up of two comfort layer sections 104 a, 104 b that are arranged side by side, and a single support layer section 106. In this embodiment, the comfort layer 104 could be customized on the right and left side of the mattress, but the support layer could not.

The embodiments of FIGS. 1A-1C are provided by way of example only and are not intended to be limiting. Those skilled in the art will appreciate that modular mattresses comprising a cover containing one or more comfort and support components can be provided in a wide variety of arrangements, all of which are intended to be within the scope of this disclosure.

FIGS. 2A-2C illustrate several example embodiments of covers 102 a, 102 b, 102 c (referred to generally as cover 102). As noted above, the cover 102 is configured to surround and enclose the internal components (e.g., the comfort layer 104 and/or the support layer 106). The cover 102 is configured to be removable. A removable cover 102 allows access to the internal components such that the can be independently removed and replaced as desired. A removable cover 102 also allows the cover to be removed for cleaning. For example, in some embodiments, the removable cover 102 is machine-washable, such that it can be removed, washed, and replaced. Further, the removable cover 102 also allows access to the interior of the mattress. During use of a mattress, dead skin, food crumbs, hair, and other debris can work their way into the interior of a mattress. In conventional mattress, this debris remains trapped within the mattress. The removable cover 102 allows access to the interior of the mattress such that any such debris can be removed, for example, by vacuuming. Thus, the removable cover 102 can improve the cleanliness of the modular mattress.

In some embodiments, the cover 102 is made from a fabric material. For example, the fabric material can be a stretch knit fabric. In some embodiments, the fabric is an aloe-vera stretch knit fabric. Other types of fabric can also be used. The fabric can be selected for indoor and/or outdoor use. In some embodiments, the cover 102 can be configured such that the mattress can be used outdoors, for example, as part of a piece of patio furniture. The fabric can be flame resistant or flame retardant. The fabric can provide a fire barrier. In some embodiments, the fabric comprises a non-skid fabric that helps to maintain the mattress in place.

FIG. 2A illustrates a first embodiment of the cover 102 for a modular mattress. The cover 102 includes a base portion 110 and an upper portion 108. The base portion 110 is connected to the upper portion 108 by a hinge 112. The hinge 112 may be formed by sewing the base portion 110 to the upper portion 108 or forming the base portion 110 and the upper portion 108 from a continuous piece of fabric. Each of the upper portion 110 and the base portion 110 can include a fastener 114 for securing the upper portion 110 to the base portion 110. In the illustrated embodiment, the fastener 114 comprises a zipper, although other types of fasteners, such as hook and loop, snaps, buttons, etc. are possible. In use the fastener 114 can be undone so as to allow access to an interior region 116 within the cover 102 a. A comfort layer 104 and a support layer 106, for example, can be inserted into the interior region 116, and then the fastener 114 can be reattached to secure the cover 102 a around the comfort layer 104 and the support layer 106.

FIG. 2B illustrates an embodiment of a two-piece cover 102 b for a modular mattress. The cover 102 b is, in some respects, similar to the cover 102 a discussed above, except that the upper portion 108 is fully removable from the base portion 110. This can be achieved by extending the fastener 114 entirely around the upper portion 108 and the base portion 110.

FIG. 2C illustrates another embodiment of a two-piece cover 102 c for a modular mattress. In this embodiment, the upper portion 108 is configured to extend over the base portion 110 in a manner that is similar to a fitted-sheet. Thus, as shown, the upper portion 108 and the base portion 110 may overlap on the sides of the mattress. In some embodiments, the upper portion 108 may further partially overlap a bottom surface of the mattress and/or the base portion 110 may partially overlap a top surface of the mattress. In some embodiments, the edges of the upper portion 108 and/or the base portion 110 can include an elastic fastener 114 for securing the cover 102 c in place.

FIG. 3 is an exploded view of an embodiment a modular mattress 100 with a cover removed. As with the modular mattresses 100 a, 100 b, 100 c of FIGS. 1A-1C, the modular mattress 100 of FIG. 3 includes a comfort layer 104 and a support layer 106. The comfort layer 104 can be similar to the comfort layers previously described.

In the illustrated embodiment of FIG. 3, the support layer 104 includes a first layer 120 and a second layer 122. The first layer 120 can be joined to the second layer 122 at a seam 124. The first layer 120 can be joined to the second layer 122 by any appropriate method, including, for example, adhesives, stitching, etc. As described previously, the user can select the support layer 106 from among a plurality of firmness options (e.g., extra soft, soft, medium, firm, extra firm, etc.). This may still be the case with the embodiment of FIG. 3, but the double layer construction of the support layer 106 may permit even greater customization. For example, the first layer 120 can comprise foam of a first density, and the second layer 122 can comprise foam of a second density that is different than the first density. The user can than select between the two densities by flipping the support layer 106 such that either first layer 120 or the second layer 122 faces up. Thus, a user can customize the modular mattress 100 by selecting a desired support layer, and then can further customize the modular mattress 100 by selecting reversing the orientation (flipping the support layer 106),

In some embodiments, various dual-layer support layers 106 can be provided. For example, dual-layer support layers 106 can be provided that are extra soft, soft, medium, firm, and extra firm, and each can have two associated degrees of firmness (provided by the first layer 120 and the second layer 122). For example, the extra soft dual-layer support layers 106 can include a first layer 120 that is first degree of extra soft and a second layer 122 that is a second degree of extra soft. Thus, by providing five dual-support layers 106, ten different firmness levels can be achieved. Those of skill in the art will understand that the described five-dual support layers 106 are provided only by way of example and other numbers of dual-support layers 106 can be provided as desired.

In some embodiments, dual-layer support layers 106 can have first and second layers 120, 122 of disparate degrees of firmness. For example, a dual-layer support 106 can include a first layer 120 that is extra soft and a second layer 122 that is extra firm.

In some embodiments, two dual-layer supports 106 can be provided in a side-by-side arrangement as shown in FIGS. 1B and 1C.

Additional support layers 106 will now be described with reference to FIGS. 4A-8. As will become apparent from the following description, the support layers 106 of FIGS. 4A-8 permit even more customization and modularity for a mattress 100. The support layers 106 can be used with the comfort layers 104 and in any of the modular mattresses 100 (e.g., the modular mattresses 100 a, 100 b 100 c) previously described.

In some embodiments, the support layers can comprise an encasement that includes a recess formed therein. The recess can be configured to receive a plurality of modular support sections or components. The modular support components can be provided in a plurality of different support levels (e.g., extra soft, soft, medium, firm, extra firm, etc.) and can be arranged within the recess of the encasement in a wide variety of different configurations to achieve a high degree of modularity and customization. Further, the components (e.g., the encasement, the modular support sections, and the modular support components) can all be selected and replaced individually providing the benefits previously described.

FIGS. 4A and 4B are isometric and cross-sectional views of an embodiment of an encasement 126 for a modular mattress 100. The encasement 126, together with one or more modular support sections or components (see FIGS. 5A-6B, for example), may make up a support layer 106 of the modular mattress 100.

In the illustrated embodiment, the encasement 126 comprises a frame 128. The frame 128 may be made from foam. The foam may be a high density foam, although other types of foam can be used. A recess 130 can be formed into the encasement 126. As will be discussed below, the recess 130 is configured to receive one or more of the modular support sections or components. The recess 130 can be surrounded by the frame 128. The recess 130 can be formed into an upper surface of the encasement 126 and extend towards a lower surface of the encasement 126. In some embodiments, the recess 130 is bounded on the bottom by a bottom layer 132. The bottom layer 132 may comprise foam that is similar to or different than the foam of the frame 128. In some embodiments, the recess 130 extends entirely through the encasement 126.

As noted above, in some embodiments, the support layer 106 is between about 4 and 12 inches thick, although other thicknesses are also possible. In some embodiments, the support layer 106 is about 8 inches thick. As such, the encasement 126 can be about 4 and 12 inches thick, although other thicknesses are also possible. In some embodiments, the encasement 126 is about 8 inches thick. The recess may extend about 50%, 75%, 80%, 85%, 90%, 95% or 100% of the way through the encasement 126 from the upper surface towards the lower surface. In some embodiments, the recess 130 extends to within about 1 inch, about 2 inches, about 3 inches, or about 4 inches of the bottom surface of the encasement 130. In some embodiments, the bottom layer 132 is about 1 inch, about 2 inches, about 3 inches, or about 4 inches thick. In some embodiments, the recess 130 is about 7 inches deep.

The recess 130 comprises an outline or profile 132. The profile 132 can comprise a wide variety of shapes. In the illustrated embodiment, the profile 132 provides a keyed profile. As used herein, a keyed profile comprises features that engage with corresponding features of an adjoining component. The keyed profile can be configured to engage with one or more of the modular support sections or components to help secure the modular support sections or components in place within the recess. In the illustrated embodiment, the keyed profile comprises a hexagonal or honeycomb outline configured to engage with the hexagonal or honeycomb shaped modular support sections or components shown in FIGS. 5A-6B. Other profiles, both keyed and non-keyed are also possible.

FIG. 5A illustrates a top view of an embodiment of three modular support sections 134 a, 134 b, 134 c (referred to generally as modular support section 134) for a modular mattress 100. In some embodiments, the modular support sections 134 a, 134 b, 134 c are configured to be received within the recess 130 of the encasement 126. In the illustrated embodiment, three modular support sections 134 a, 134 b, 134 c are provided. Modular support section 134 a can be a head section, modular support section 134 b can be a torso section, and modular support section 134 c can be a foot section. In some embodiments, other numbers of modular support sections 134 can be provided, for example, two, three, four, five, six, etc.

Each modular support section 134 can be provided with the same options described above with reference to the support layer 106. That is, modular support sections 134 can comprise foam with different degrees of firmness (e.g., extra soft, soft, medium, firm, extra firm, etc.). Thus, by selecting different modular support sections 134, the user can customize different regions of the support layer 106. For example, a user could select a soft head section, a firm torso section, and an extra soft foot section. Further, a user can advantageously replace one or more of these sections individually from the other components of the mattress as desired.

As shown in the side view of FIG. 5B, a modular support section 134 can comprise a dual-layer construction. For example, each modular support section 134 can include a first layer 136 and a second layer 138. The first layer 136 can be joined to the second layer 138 at a seam 140. The first layer 136 can be joined to the second layer 138 by any appropriate method, including, for example, adhesives, stitching, etc. As described previously, the user can select the modular support sections 134 from among a plurality of firmness options (e.g., extra soft, soft, medium, firm, extra firm, etc.). The double layer construction of the support modular support section 134 as shown in FIG. 5B may permit even greater customization. For example, the first layer 136 can comprise foam of a first density, and the second layer 138 can comprise foam of a second density that is different than the first density. The user can than select between the two densities by flipping the modular support structure 134 such that either first layer 136 or the second layer 138 faces up.

In some embodiments, various modular support sections 134 can be provided. For example, dual-layer modular support sections 134 can be provided that are extra soft, soft, medium, firm, and extra firm, and each can have two associated degrees of firmness (provided by the first layer 136 and the second layer 138). For example, the extra soft dual-layer modular support sections 134 can include a first layer 136 that is first degree of extra soft and a second layer 138 that is a second degree of extra soft. Thus, by providing five dual-support modular support sections 134, ten different firmness levels can be achieved. Those of skill in the art will understand that the described five-dual modular support sections 134 are provided only by way of example and other numbers of dual-layer modular support sections 134 can be provided as desired.

The thickness of modular support sections 134 can be configured to match the depth of the recess 130.

As shown in FIGS. 5A and 5C, the modular support sections 134 can comprise an outline or profile 142. The profile 142 can be configured to engage with the profile 132 of the recess 130 of the encasement, as well as with the profiles 142 of adjacent modular support sections 134 (or modular support components as described below with reference to FIGS. 6A and 6B). In some embodiments, the profile 142 is a keyed profile. The keyed profile may comprise a hexagon or honeycomb profile as described above. Other profiles are also possible.

FIG. 5C illustrates a top view of an embodiment of modular support section 134. The modular support section can include a plurality of individual sections 146. The sections 146 may be hexagonal in shape, although other sections are possible. The sections 146 can be separated by perforations 144. If desired, one or more individual section 146 can be removed by tearing or cutting along appropriate perforations 144. The removed sections 146 can be filled and reinserted into the modular support section 134 or replaced with other modular support components (as shown in FIGS. 6A and 6B).

FIG. 6A illustrates a top view of an embodiment of a plurality of modular support components 150 disposed in the encasement 126 of a modular mattress 100. FIG. 6B illustrates an isometric view of an embodiment of a single modular support component 150.

As shown, the recess 130 of the encasement 126 can be filled with a plurality of modular support components 150 to provide a fully customizable support profile for the support layer 106. That is, each modular support component 150 can be selected so as to provide a different level support at the corresponding location into which the modular support component 150 is inserted. In the illustrated embodiment, the encasement 150 is configured to hold 60 different modular support components 150. This allows for 60 different locations of adjustable support. In some embodiments, other numbers of support components 150 can be used. For example, the encasement can be configured to hold 10, 20, 30, 40, 50, 60, 70, 80, 100, or more modular support components 150.

Each modular support component 150 can be provided with the same options described above with reference to the support layer 106. That is, modular support components 150 can comprise foam with different degrees of firmness (e.g., extra soft, soft, medium, firm, extra firm, etc.). Thus, by selecting different modular support components 150, the user can customize different regions of the support layer 106. For example, a user could select a soft head section, a firm torso section, and an extra soft foot section. Further, a user can advantageously replace one or more of these sections individually from the other components of the mattress as desired.

As shown in the side view of FIG. 6B, a modular support component 150 can comprise a dual-layer construction. For example, each modular support component 150 can include a first layer 152 and a second layer 154. The first layer 152 can be joined to the second layer 154 at a seam 156. The first layer 152 can be joined to the second layer 154 by any appropriate method, including, for example, adhesives, stitching, etc. As described previously, the user can select the modular support components 150 from among a plurality of firmness options (e.g., extra soft, soft, medium, firm, extra firm, etc.). The double layer construction of the support modular support component 150 as shown in FIG. 6B may permit even greater customization. For example, the first layer 152 can comprise foam of a first density, and the second layer 154 can comprise foam of a second density that is different than the first density. The user can than select between the two densities by flipping the modular support component 150 such that either first layer 152 or the second layer 154 faces up.

In some embodiments, various modular support components 150 can be provided. For example, dual-layer modular support components 150 can be provided that are extra soft, soft, medium, firm, and extra firm, and each can have two associated degrees of firmness (provided by the first layer 152 and the second layer 154). For example, the extra soft dual-layer modular support components 150 can include a first layer 152 that is first degree of extra soft and a second layer 154 that is a second degree of extra soft. Thus, by providing five dual-support modular support components 150, ten different firmness levels can be achieved. Those of skill in the art will understand that the described five-dual modular support components 150 are provided only by way of example and other numbers of dual-layer modular support components 150 can be provided as desired.

The thickness of modular support components 150 can be configured to match the depth of the recess 130.

As shown in FIG. 6B, the modular support components 150 can comprise an outline or profile 158. The profile 158 can be configured to engage with the profile 132 of the recess 130 of the encasement, as well as with the profiles 158 of adjacent modular support components 150 (or modular support sections 134 as described below with reference to FIGS. 5A-5C). In some embodiments, the profile 158 is a keyed profile. The keyed profile may comprise a hexagon or honeycomb profile as described above. Other profiles are also possible. For example, the modular support components 150 can comprise a circular, triangular, square, rectangle, other polygonal, or other shape profile 158.

In some embodiments, a modular mattress may utilize both modular support sections 134 and modular support components 150. For example, a user may select a head modular support section 134 a and a foot modular support section 134 c, and then fill the remaining section with a plurality of modular support components 150. Further, a user may remove a section of a modular support section 134 (e.g., using perforations 144) and replace the removed sections with one or more modular support components.

The use of modular support sections 134 and/or modular support components 150 can create a highly customizable and modular mattress 100.

FIG. 7 illustrates a top view of an embodiment of a modular mattress 100, including two encasements 126 a, 126 b arranged side by side, each encasement 126 including a plurality of modular support components 150. As shown, the mattress provides a high degree of customization by allowing different modular support components 150 to install at different locations.

FIG. 8 is a top view of a modular mattress illustrating example dimensions of certain components according to one embodiment. The illustrated dimensions are provided by way of example only and should not be construed as limiting.

FIG. 9 is an exploded view of an embodiment of a modular mattress. The mattress includes a top layer 104, a base layer 190, an encasement 190 and a plurality of modular support components. FIG. 10 is an exploded view of another embodiment of a modular mattress. The mattress includes an encasement 126 and three modular support sections 134. The mattress may also include a top layer and a base layer.

In some embodiments, a doctor or chiropractor may provide information or otherwise help customize a modular mattress for a particular user.

The modular mattresses described herein can be adapted for use as pet beds. For example, a smaller encasement can be configured to receive a single modular support section and/or a plurality of modular support components for us with a dog or cat.

An example of a modular and adjustable mattress 200 is shown in FIGS. 11 and 12. In the illustrated embodiment, the mattress 200 comprises an encasement 202 and two modular inserts 204 (or modular component 204). In the figures, the modular inserts 204 comprise a left modular insert 204A, on the left side of the mattress 200, and a right modular insert 204B, on the right side of the mattress 200. Although the illustrated embodiment includes two modular inserts 204, in other embodiments, the mattress 200 may include a single modular insert 204. Such a mattress 200 (including a single modular insert 204) may be suitable, for example, for use as a twin size bed suitable for use by a single person. The illustrated embodiment, including left and right modular inserts 204A, 204B, may be suitable for mattress sizes generally accommodating two people, as the left and right modular inserts 204A, 204B can allow for independent adjustment and customization of the left and right sides of the mattress 200 as will be described below.

As shown in FIGS. 11 and 12, the modular inserts 204 are received in an encasement 202. The encasement 202 may comprise a recess formed therein. The recess can be configured to receive the modular inserts 204 as shown. The encasement 202 may be made from foam. The foam may be a high density foam, although other types of foam can be used. The recess can be formed into an upper surface of the encasement 202 and extend towards a lower surface of the encasement 202. In some embodiments, the recess 230 is bounded on the bottom by a bottom layer. The bottom layer may comprise foam that is similar to or different than the foam of the encasement 202. In some embodiments, the bottom layer of the encasement 202 is between one and six inches thick, for example, the bottom layer of the encasement 202 can be two inches thick or four inches thick. Other thicknesses are also possible. The bottom layer of the encasement 202 can comprise a base for the mattress 200. Above the bottom layer 202, the recess can be configured to be sufficiently deep so that when the modular inserts 204 are received therein, the modular inserts 204 are flush with the upper surface of the encasement 202.

As illustrated in FIGS. 11 and 12, and also shown in FIGS. 13 and 14 (which provide more detailed views of the left and right modular inserts 204A, 204B), each modular insert 204 may comprise different sections that comprise different textures, stiffnesses, or comfort levels. For example, as illustrated, each modular insert 204 comprises a head section 206, a body section 208, and a foot section 210. A detailed view of an example head section 206 is shown in FIG. 17, an example foot section 210 is shown in FIG. 18, and an example body section 208 is shown in FIGS. 19 and 20, which are described in more detail below. As illustrated, for some embodiments, the head section 206, the body section 208, and the foot section 210 are all connected such that each modular insert 204 comprises a single piece.

FIGS. 15 and 16 illustrate that, for some embodiments, each modular insert 204 can comprise two layers of foam. For example, as shown in FIG. 5, the left modular insert comprises a first foam layer 212 and a second foam layer 214. In the illustrated configuration, the first foam layer 212 is facing up for the left modular insert 204. As shown in FIG. 16, the right modular insert 204B also comprises the first foam layer 212 and the second foam layer 214, but is positioned such that the second foam layer 214 is facing up.

Each of the foam layers 212, 214 can be configured to provide a different stiffness of comfort level (for example, extra soft, soft, medium, firm, extra firm, etc.). The modular insert 204 can exhibit a different comfort level depending on which foam layer 212 is facing up. Thus, as shown, the mattress 200 may have a first comfort level on the left side of the mattress 200 and a second comfort level on the right side of the mattress 200. Further, users of the mattress 200 can flip the modular inserts 204 to change the comfort level. This allows the mattress 200 to be adjustable.

In some embodiments, the modular inserts 204 may also comprise additional foam layers, such as intermediary layers between the first and second layers 212, 214.

FIG. 17 illustrates a detail view of an embodiment of a head section 206 of a modular insert 204. As shown, the head section 206 can comprise a nodular or egg carton texture formed into the foam. FIG. 18 illustrates a detail view of an embodiment of a foot section 210 of a modular insert 204. Similar to the head section 206, the foot section 210 can comprise a nodular or egg carton texture formed into the foam. In some embodiments, the texture of the foot section 210 is different than the texture of the head section 206. For example, as illustrated, the nodule of the foot section 210 can be smaller than the nodules of the head section 206. Other textures can also be used for the head section 206 and the foot section 210.

FIGS. 19 and 20 illustrate detail views an embodiment of a body section 208 of an insert 204. FIG. 19 is a perspective view and FIG. 20 is a top view. As shown, the body section 208 can also comprise a texture formed into the foam. In the illustrated embodiment, the texture comprises octagons, but other shapes may be used as well. Comparing FIG. 19 with FIGS. 17 and 18, it can be seen that, in some embodiments, the texture of the body section 208 is not as deeply formed as the texture of the head and/or foot sections 206, 210. This need not be the case in all embodiments. Other textures for the body section 208 can also be used.

The textures of the head, body, and foot sections 206, 208, 210 of the modular inserts 204 can be formed in to each layer 212, 214 of the modular insert 204 such that the texture exists on both sides. This further allows the modular insert 204 to flappable or reversible as discussed above.

In some embodiments, the mattress 200 may be between 8 and 16 inches thick. For example, the mattress 200 can be 12 inches thick. In some embodiments, the modular inserts 204 are between 4 and 12 inches thick. For example, the modular inserts can be 8 inches thick. Other thicknesses are also possible. Thickness can be measured between tops of nodules opposite each other and extending from layers 212 and 214, respectively.

As described above, the mattress 200 includes modular inserts 204 that can be selected, added, removed, and/or replaced individually of the other components of the modular mattress 200. Further, the modular inserts 204 can be flipped to adjust their comfort level. This can provide one or more of the following advantages, such as, improving customization and personalization of the mattress 200, permitting the function and feel of the modular mattress 200 to change over time to adapt to changing user preferences or other conditions, facilitating replacement of old, worn, or damaged components of the mattress 200, permitting the modular mattress to be easily cleanable, decreasing waste to landfills, and increasing shipping efficiency, among others.

FIG. 21 illustrates an embodiment of a modular mattress 300 including a reversible topper 302. The reversible topper 302 can be configured to be placed over additional modular components as shown below in FIG. 22. In some embodiments, the reversible topper 302 can be used with the mattresses 100 and 200 described above to provide additional customization, which can increase a user's ability to have a comfortable mattress that works well for their body.

In the illustrated embodiment, the reversible topper 302 comprises a first layer 304 and a second layer 306. The first and second layers 304, 306, can each be made from a different material or comprise a different density such that the reversible topper can provide different feels depending on the orientation. For example, when the first layer 304 is oriented upwardly, the reversible topper can provide a different feel than when the second layer 306 is oriented upwardly. At any time, the user can reverse the orientation of the reversible topper to further customize the feel of the mattress 300.

In one example, the first layer 304 comprises latex and the second layer 306 comprises memory foam, such as a temperature and pressure neutral memory foam. Other materials can also be used for the layers 304, 306, such as any of the materials previously described.

As shown in FIG. 21, the mattress 300 can also include additional modular components, which can be similar to modular components previously described with reference to the mattresses 100 and 200. For example, in the illustrate embodiment, the mattress 300 comprises an encasement 308. Although not visible in FIG. 21, the encasement 308 can include a recess into which additional modular components can be inserted as described below. By adjusting the additional modular components, the user can further customize the performance of the mattress 300 in addition to the adjustments provided by the reversible topper 302.

In the illustrated embodiment, of FIG. 21, the mattress also includes a cover 310. In some embodiments, the cover 310 is configured to enclose both the reversible topper 302 and the encasement 308 (and additional modular components included therein). In some embodiments, the cover 310 is configured to enclose the encasement 308 (and additional modular components included therein) and the reversible topper 302 includes its own cover. In some embodiments, the cover 310 can be removable. For example, as illustrated the cover 310 includes a zipper such that it can be opened.

The illustrated embodiment of FIG. 21 shoes an example of a 12 inch mattress including a reversible topper 302, a straight encasement 308 (having a recess with straight sides as described below (as opposed to the geometric shaped sides described above), and various other modular components as described below.

FIG. 22 illustrates the mattress of FIG. 21 with the reversible topper 302 raised up so as to show additional modular components 312 underneath. In the illustrated embodiment, the modular component 312 can include different head, torso, and feet zoning as described above, which can provide customizable support for each body part. Further, the modular component 312 can be removed and replaced with additional modular components as desired to adjust the feel. In some embodiments, the modular component 312 is reversible, providing a first level of comfort in a first orientation and a second level of comfort in a second orientation.

FIG. 23 illustrates the mattress 300 of FIG. 21 with the reversible topper 302 removed and some of the modular components 312 removed. In this view, the modular components 312 on one side of the mattress 314 have been removed such that the recess 314 on that side of the mattress 300 is empty. In the illustrated embodiment, the recess 314 has straight sides and is configured for use with straight-sided modular components 312. In other embodiments, the recess 314 can comprise a geometric profile as described above and can be configured for use with modular components 312 that also comprise a corresponding geometric profile.

FIG. 23 also illustrates that, for some embodiments, a modular component 312 can extend across the entire length of the recess 314. As illustrated, the modular component 312 extends entirely from the head to the foot of the recess 314. The different zoning patterns on the head, torso, and feet section of the modular component 312 can be seen. Also shown in FIG. 23, the modular component can comprise two foam layers. Use of two foam layers can allow the modular component to be reversible such that the comfort level can be customized and adjusted as desired.

FIG. 24 illustrates the mattress of FIG. 21 with the reversible topper raised 302 and additional modular components 312 installed. As shown in FIG. 24, three modular components 312 can be installed on the left side (relative to the orientation shown in the figure) of the mattress 300. Each of these modular components 312 can comprise a different material that can provide different comfort levels. A user can select different modular components 312 to provide different support for head, torso, and feet regions of the mattress. Further, the components 312 can be reversible described previously to allow for further adjustment. FIG. 24 also shows that each side of the mattress 300 can comprise different modular components such that each partner can adjust the feel of the mattress 300 as desired.

FIG. 25 illustrates an additional view of some of the modular components 312 of the mattress of FIG. 21. As shown, each modular component 312 can comprise two layers of foam or two different materials. This allows the modular components 312 to be reversible as described above. This figure also illustrates the modular components 312 can have straight edges that corresponding with the straight edges of the recess 314 of the encasement.

FIGS. 26 and 27 are top and bottom views of an embodiment of one of the modular components 312 for the mattress of FIG. 21. In this embodiment, the two layers of the modular component 312 can be seen. FIG. 27 illustrates that one side of the modular component can be configured with different zoning for head, torso and foot regions.

The mattress 300 can provide a high level of customization. For example, a user can select different modular components 312 and select an orientation of the reversible topper 302. Further, the modular components 312 can extend across an entire length of the recess 314 of the encasement, can comprise zoned components (such as head, torso, and feet) components, or can comprise smaller section components similar to the smaller components 150 described above. Additionally, the any or all of the modular components can be reversible providing even further customization. This can allow a user to dial in a very precise comfort level.

FIG. 28 illustrates another embodiment of a modular mattress 400, which illustrates the high degree of customization achievable. In the illustrated embodiment, the mattress 400 includes right and left sides (relative to the orientation shown in the figure). Each side includes its own encasement 408 having a recess formed therein. In other embodiments, the mattress 400 may have a single encasement 408 with a large recess that extends across both sides. Further, in the illustrated embodiment, the encasements 408 comprise a geometric profile, although it is possible to configure the encasements 408 with straight-sided profiles as well.
